This seems like an obvious curiousity, but I have yet to find a good explanation: If I want to scan a photo, say a little photo 2x3 to put in, say, the corner of a document, what good does it do to have the capability of scanning and printing at 300 dpi if the only way to 'work with' the image on-screen requires a much lower resolution (or a scaling-down which would lose resolution data)? In other words, how do I scan and print at the higher resolutions when I have to use the monitor to place and position the image in the document? Any help is appreciated.

Jim,
If it's an HTML document you can "force" the physical
image size to be smaller and still retain the larger more defined
file size. Without the starting and ending brackets so it will
show up here, this is what the the address of a picture looks
like: img src="file:///G:/PHOTO_9/5400-3.jpg"
width="640"
height="480" Now you can see that the browser is being
told that it's a 640x480 .jpg but by changing the size to 320x240
in the HTML the photo will be forced to appear smaller but it
actually is a 640x480 pic. If you end up with odd size pictures
remember to maintain the aspect ratio. -Helene

Thank you, Helene, that is understandable. I was actually wondering about putting a scanned image in Word document, though, and retaining higher resolution for printing purposes while 'handling' the picture on-screen while positioning it. I know it's probably an overly-basic question but it has me befuddled.
Editor's Note: Jim later wrote:
Turns out in my amateur way of looking at things, that I didn't consider the image that prints can have a 'different' resolution than the number of pixels on the screen that are used to represent it. The screen image is just a 'copy' of the image and adjustment is made on-screen so that we can see it in the dimensions we are thinking about it (2x2 or whatever). The image has its internal 'record' of its actual resolution, so your printer gets sent more data than the monitor is showing. You are then only limited by your printer's specs.
